A An increase in the number of stromules formed by chloroplasts harboring the HyPER protein which scavenges H2O2 or a GFP which does not scavenge H2O2 (control plants) was observed. HyPER fluorescence (green) and autofluorescence of the chloroplasts (red) and a merge of these are presented. B The highest average number of stromules per chloroplasts in leaves of the chloro-35S:HyPER line and the control plants, which was counted over different developmental stages, is indicated. C Stromules are able to contact the nucleus shown in a merged microscopic image of transmitted light, HyPER fluorescence (green) and autofluorescence of the chloroplasts (red)
